Explanation

The sentence "They invited us to their home yesterday" is in the past indefinite tense. 

This tense is used to express actions that happened at a specific time in the past, and the time is mentioned or implied.

In this case, the time is mentioned as "yesterday."

Explanation

We use "for" with a period of time in the past, present, or future.

We use since with a point in time in the past.

For refers to periods of time, e.g. 3 years, 4 hours, ages, a long time, months, years.

Explanation

Ten years ago, the earthquake destroyed the city. دس سال قبل زلزلے نے شہر کو تباہ کردیا تھا۔

We normally use ago with the past simple.

We don't use it with the present perfect: I received his letter four days ago.

Not: I have received his letter four days ago.

We should use past indefinite tense for a point of time.
